We are a licensed and insured engineering firm with experience across a wide range of projects — from residential remodels and additions to multi-story buildings and commercial tenant improvements. Our team brings not only design knowledge, but also field experience, which means we understand how projects get built, not just how they look on paper. What makes us stand out is our commitment to clarity, responsiveness, and integrity. We don’t just provide stamped drawings; we provide peace of mind. Whether you’re a homeowner, architect, contractor, or developer, we listen carefully, communicate clearly, and take pride in delivering engineering that works — practically and code-compliantly. With CedarLine, you’re not just hiring an engineer — you’re gaining a dependable partner who’s invested in the success of your project. Our services include: Structural design for load-bearing wall removals, remodels, additions, decks, retaining walls, and foundations. Civil/site plans for grading, drainage, right-of-way permits, stormwater design (WWHM 2012, SWPPP), and utility coordination. Land development services including subdivisions, short plats, and lot line adjustments. Permit support and coordination with local cities and counties. Structural inspections and reports for lenders, buyers, and homeowners. We pride ourselves on clear communication, practical solutions, and efficient turnaround. Site visits start at $350, and we provide sealed drawings and reports as required for permit submittals.

From Google

We had an excellent experience working with Morteza and his team at CedarLine Engineering. They helped us thoroughly assess the structural integrity of a new home we purchased, and their expertise gave us real confidence.Morteza is extremely knowledgeable about permitting requirements and structural design standards in Seattle, which was incredibly valuable. He and his team were professional, responsive, and detail-oriented throughout the entire process.I highly recommend CedarLine Engineering to anyone in need of structural engineering services.

Our experience was absolutely first-rate: we received crucially valuable information and inventive ideas, fully and clearly expressed.The engineer met with our contractor, regarding a garage rdemodel--raising the floor more than two feet and reconfiguring a space of 625 sq. ft. Brilliant, cost-effective and comprehensive solutions!

Mr. Ebrahimi responded promptly following my initial inquiry on Thumbtack. We had an in depth discussion regarding my project over the phone after providing some rudimentary pictures and information. He seemed to go out of his way to help me remotely and find time to accommodate my schedule within a week. His on-site review and discussion of the project was thorough and straightforward. Would recommend his services to anyone seeking structural and whole-view expertise.

Hired on Thumbtack

The engineer explained everything clearly. He let us know what steps to take to fix our drainage problem and how to fix the hole under our backyard art studio. His recommendation was more reasonably priced than the other guys solution. And he showed us why the less expensive route would work better for our situation. We trust him and would hire him again for any engineering we may need in the future. He was pleasant to work with as well.
